Legal claims defining the scope of protection, as filed with the USPTO.

1

1. An image processing device comprising: an image data generator generating a first image data which is image information for each pixel and which includes a plurality of color data, said color data representative of red (R), green (G), and blue (B) values, and when performing an output of said image data said first image is output concurrently to both an image processor and image data output unit; said image processor including a color converter, and calculating, based on the R, G, B values of the first image data and the color reproduction characteristics of a display unit, a second image data, which include a plurality of said color data representative of said red (R), green (G), and blue (B) values different from said first image data in said color space, by performing image processing including color conversion on the first image data; said image display unit displaying an image using the second image data; and said image data output unit for outputting the first image data to the outside.

2

2. The image processing device as set forth in claim 1 , wherein said image data generator generates the first image data as a digital data, and said image data output unit outputs the first image data after conversion into an analog data.

3

3. The image processing device as set forth in claim 1 , wherein said image processor further includes a tone converter for converting the tone of the image data having been color-converted by the color converter.

4

4. The image processing device as set forth in claim 1 , wherein said image processor further includes a dither processor for performing dither processing on the image data having been color-converted by the color converter.

5

5. The image processing device as set forth in claim 1 , wherein said color converter includes a coefficient generator generating predetermined matrix coefficients, an arithmetic term calculator calculating a plurality of arithmetic terms each of which is effective for only a specific hue among a plurality of hues, and a matrix calculator performing matrix calculation on the matrix coefficients and the plurality of the arithmetic terms each of which is effective for only the specific hue.

6

6. The image processing device as set forth in claim 5 , wherein said plurality of hues include six hues of red, green, blue, cyan, magenta, and yellow.

7

7. The image processing device as set forth in claim 1 , wherein said color converter includes a coefficient generator generating predetermined matrix coefficients, an arithmetic term calculator calculating a plurality of arithmetic terms each of which is effective for only a region between adjacent hues, among a plurality of hues, and a matrix calculator performing matrix calculation using the matrix coefficients and the plurality of arithmetic terms each of which is effective for only said region between the hues.

8

8. The image processing device as set forth in claim 7 , wherein said plurality of hues include six hues of red, green, blue, cyan, magenta, and yellow.

9

9. A method of processing image data, comprising: obtaining image data by an image data generator; generating a first image data, which is image information for each pixel, from the image, the first image data including an exact color representation of the image data corresponding to red (R), green (G) and blue (B) values, where at each output of said image data generator said image data is provided concurrently to both an image data output unit and a color converter; generating a second image data of said color converter by converting the R, G, B values of first image data based on color reproduction characteristics of a display device so that the second image data includes color characteristics of said display device and is representative of said red (R), green (G), and blue (B) values different from said first image data in said color space; outputting the second image data to the display device; and outputting the first image data from said image data output unit, this output being a separate output from the output of the second image data.
